While your observations are most probably correct, it stands as a fact that evaluation order
of multiple pre/post-increments in one statement isn't explicitly defined in Perl 5, I guess
on purpose. It is an artifact of the implementation of Perl - it is not in the language specs
afaik - so you shouldn't rely on it, even if all perl 5 binaries we know of stack execution in
the way you describe.
And that is more than saying "while you can use multiple pre/post-increments in a single statement,
it is bad practice and should be avoided" - it is saying "it's not defined. Don't".
